I have only bred my yorkie once, and won't be doing it again... I have no problems saying that, and I don't give out breeding advice, unless I am certian of what I am talking about.
I don't care if I am critized for only breeding once, it wasn't my intention. My intention was to become a hobby breeder- but since my mom went into a continual heat after welping, which made her uncomfortable, I got her fixed.
I could of continued on breeding her or her pup in the future, but honestly breeding isn't for me- I don't have the heart to raise them then sell them, I had no problems with this when I raised birds, but the yorkies were different for me. I got way too attached, and I admit with them and my birds, all I did was worry.
Of course then after making the decision I found out that my female pup that I kept, and got spayed, had a problem with her tear ducts (not fully forming) which is sad, but it really sent the message home to me that I made the right decisions.
I had done a lot of research, talked to my mentor and read everything I could on the internet... so I do have some knowledge even if I only bred once, which I believe others here do the same, so I wouldn't discount their support or knowledge.
Don't know why I felt the need to explain that I only bred once, I suppose it makes my first post on this thread mean nothing now- but like everyone here I was just sharing my experience.
I do wish however, that this place was more supportive to those asking questions, because in the end, most will do what they want- isn't it best for them the yorkie and the pups to have the most knowledge possible?
Good luck, I do hope it all works out with you, and I hope your vet is able to answer your questions regarding the teeth
